MOLDERS-SAND-CUTTING MACHINE.

Specification of Letters Patent.

Patented Jan. 13, 1914.

Application filed June 14, 1913. Serial No. 773,796.

To all whom it may concern;

Be it known that I, ROMAN-Gr. KissnL, a citizen of the United States, residing at De Kalb, in the county of Dekalb and State of Illinois, have inventeda new and useful Improvement in Molders-Sand-Cutting Machines, of which the following is a specification.

The sand used for molding in foundries becomes strewn over the floor, and it is customary to gather it into a pile, from which it is taken for use, by shoveling it by hand, which is a laborious and expensive operation.

The object of my invention is to provide a machine for gathering or cutting this sand, thereby to facilitate and expedite handlihg it in the operation of molding in foundries, and render the work more economical in time and labor.

In the accompanying drawings, Figure 1 shows my molders-sand cutting-machine by a view,in side elevation, Fig. 2 is a top plan View of the machine; Fig. 3 is aview of the same in'rear elevation; Fig. .4

is a. view in elevation of one side of the frame,and Fig. 5 is a section-on line '5,- Fig.2. 1

- The carriage-frame of the machine consists of two side-members 6 and 7, each having depending centrally from it a yoke 8, the side-members being. rigidl connected together by a tie-bar 9 extendmg between the yokes at their lower ends. The endposts of each side-member are provided on their ends with axle-bearings 10, 11, 12 and 13, while on the member"? adjacent to. its rear post is formed a laterally outward extending sleeve-bearing 14. n the lower bearings 11 and 13 are supported, res ectively, the axles 15 and 16 carrying on t eir ends the carriage-wheels 1'}; A crank-shaft 18 is journaled atits ends in the framebearings 10, and a similar crank-shaft 18 is journaled at its ends in the frame-bearings 1.2, each of these shafts bein formedwith four elongated cranks. Lin -bars 19 pivotally connect together the corresponding crankson the two {crank-shafts, these bars having bifurcated ends formed with segmental rack-heads 20. In the bifurcated end of each bar 19 is pivoted at 21, through its straight end, an upwardly-curved handle 22 terminating at its opposite end in ablade holder 24 and adj ustably fastened to the bar by a pin 22 inserted through it and through coincident holes in i the rack 20. Each handle extends through a notch 23 formed in the upper end of an arc-shaped blade 23, which is. riveted to the blade-holder. The outer blades are supported on the holders to extend therefrom laterally at an angle of about sixty degrees, more or less, thus projecting the inner edge of each outer blade ahead of its rear edge for the purpose herelnafter explained.

.A gear-wheel 25 on a carriage-wheel 17 meshes with an idler 26 journaled in the bearrng 14; and this idler meshes with a gear 27 secured on an end of the crankshaft 18'.

The machine may be dragged over the molding fioor through the medium of a tongue 28, indicated as being pivoted to the axle 15, or by a suitable motor (not shown) which may be carried on the machine and geared to the wheel26. 1

In operating the machine by moving it over a foundry-floor, the gear 26 drives the gear 27 to turn the crank-axle 18, thereby turning both crank-axles and, by their barconnections 19, working the blades to the floor-level to shovel the sand into a pile underneath the machine as it advances. By the angular setting, referred to, of the outer blades, they work the sand to the two middle blades, thereby producing a desirably thorough mixture of the sand andaccumulating it into a heap of general triangular shape, as has hitherto been done by hand.

Preparatory to moving the machine about, when not operating, to reduce it to journaled on said posts, bars pivotally connecting corresponding cranks of said shafts,

gearing connected with one crank-shaft for driving the shafts, and shovels supported on the rear ends of said bars to be operated by the cranks in the forward movement of the machine to actuate the bars to work the shovels in the direction of said movement over the floor-level, the two outer shovels being set to extend at an angle to the line of draft and sweep the sand on said level into the path of the intermediate shovels.

2. A machine of the character described, comprising a wheeled carriage having posts on opposite ends of its frame, crank-shafts journaled on said posts, bars pivotally connecting corresponding cranks of said shafts, shovels having handles at which they are 'adjustably connected with the bars at one end thereof, and gearing connected with one crank-shaft for driving the shafts to work the shovels over a floor-level, for the purpose set forth.

3. A molders sand-cutting machine, comprising a wheeled carriage having posts on opposite ends of its frame carrying on their lower ends the wheel-axles, crank-shafts journaled on the upper ends' of the posts to Work above the axles, bars pivotally connecting corresponding ends of said shafts, earin'g connected with one crank-shaft for riviiig the shafts, and shovels supported on the rear end of said bars to be operated by the cranks in the forward movement of the machine to actuate the bars to work the shovels in the direction of said movement over the floor-level.
